Study of the regioselectivity of intra- and intermolecular glycosylations of mannoside diol acceptors

The intramolecular glycosylation of thiomannoside donors linked through C6′ by a phthaloyl group to C3 of a diol mannoside acceptor is described. The unexpected results led us to undertake a systematic analysis of the factors affecting the regioselectivity of the intermolecular process. The substituents on the diol mannoside acceptor have been found to play an important role.
